How to use maintenanceWindows?

[binhnguyenduc]

Please, answer some short questions which should help us to understand your problem / question better?

• Which image of the operator are you using? e.g. registry.opensource.zalan.do/acid/postgres-operator:v1.6.3
• Where do you run it - cloud or metal? Kubernetes or OpenShift? Bare Metal K8s
• Are you running Postgres Operator in production? yes
• Type of issue? question

I cannot seem to find documentations for the field maintenanceWindows in Postgresql CRD. If I understand correctly, that is used to indicate that no operator action can be performed outside of those time slot. Is that true?

If that were true, we would definitely be interested in that feature. Please point me to the relevant documentation.

Thanks so much for your awesome works!

Looks like they've been around since forever, but are still not implemented. Can't tell what the original idea was. Probably, only allow rolling updates (Spilo udates etc.) during those windows. But not sure.

Looks like this is now possible with:
